This PR adds the script gmsaMembership.py to impacket.

The ms-DS-GroupMSAMembership attribute is used to determine if a requestor has permission to retrieve the gMSA password. It contains a security descriptor in the String(NT-Sec-Desc) format.

gmsaMembership.py can handle the ms-DS-GroupMSAMembership attribute of a target gMSA account. It can read the current entries, add a new one or remove the existing ones.

The script has been adopted from rbcd.py as the structure of ms-DS-GroupMSAMembership is similar to ms-DS-Allowed-To-Act-On-Behalf-Of-Other-Identity.
